Pummy is a good host.
The location is great just in front of the metro.
The apartment is very nice, well equipped and with a bathtub.
I've stay only for one night, my last in Thailand so i didn't have the time to enjoy the swimming pool. Her brother was there to welcome me for the check in, everything was good, and i had to go to the airport early in the morning.
At night it might be a bit noisy.
I recommend Pummy's flat if you are going to Bangkok.
